  • Patent number: 9199886
    Abstract: Gas-generating compositions and methods for their use are provided. Metal complexes are used as gas-generating compositions. These complexes are comprised of a metal cation template, a neutral ligand containing hydrogen and nitrogen, and sufficient oxidizing anion to balance the charge of the complex. The complexes are formulated such that when the complex combusts, nitrogen gas and water vapor is produced. Specific examples of such complexes include metal nitrite amine, metal nitrate amine, and metal perchlorate amine complexes, as well as hydrazine complexes. A binder and co-oxidizer can be combined with the metal complexes to improve crush strength of the gas-generating compositions and to permit efficient combustion of the binder. Such gas-generating compositions are adaptable for use in gas-generating devices, such as automobile air bags.

  • Patent number: 9139486
    Abstract: Method for decommissioning a body containing explosive material includes opening the body containing explosive material in a secured and/or currentless state, and cutting individual bodies along a cutting plane into at least two parts in a liquid by one or more cutting processes to expose the main charge carriers intact in the respective individual bodies for removal without destruction. Method further includes removing main charge carrier essentially intact while still in the liquid from the individual bodies, and transferring the main charge carrier to a container, structured and arranged to store each individual main charge carrier free from contact with other main charge carriers, and which includes a material that is absorbent for liquids. Method further includes feeding the container with the main charge carriers to an incineration process and grinding all of the other parts of the individual bodies in a grinding process to produce ground material.

  • Patent number: 8888935
    Abstract: A composition capable of producing either solid propellant grains, liquid or gel monopropellants, all of which are electrically ignitable and capable of sustained controllable combustion at ambient pressure. Additional compositions capable of sustained controllable combustion at elevated pressures are described. Applications for the compositions disclosed herein are provided, and include among other applications use in small micro thrusters, large core-burning solid propellant gains, shaped explosives charges for military application, and pumpable liquids and gel monopropellants or explosives for military, commercial mining or gas and oil recovery. In alternative embodiments the above compositions may also incorporate an energetic nitrate polymer, bum rate modifiers, and/or metal fuel(s). The HIPEP formulation makes it possible to ignite and sustain combustion at ambient and vacuum conditions (a) without continuous electrical power and (b) while providing faster bum rates.
